Janice Dickinson, a reality star and former model, revealed her history of abuse, alcoholism and drug addiction on the season premiere of "Celebrity Rehab" with Dr. Drew Pinsky, which aired on Wednesday.

Pinsky helps the celebrities deal with psychological and substance abuse issues at the Pasadena Recovery Center in southern California.

"I am the world's first supermodel and just all around hot mess," Dickinson says on the VH1 show. "I worked all day and partied all night. Alcohol at every shoot and there was lots and lots and lots of cocaine. It was vicious because back in the day there was no lifeguard on duty in my case. I was damaged beauty. "

She told Pinsky, in tears, that she often takes prescription sleeping pills and had suffered physical, emotional, sexual and substance abuse. She has spoken candidly in the past about her father, who she deemed a pedophile that allegedly abused her. He has not commented.

"My dad had rage issues," Dickinson said. "I was locked in car trunks, I was taped and gagged so he could go have his way. I was locked in a silent terror of a monster. I'm an alcoholic and chemically-dependant woman. I want to drink and I want to party and that's not good. "

Before "Celebrity Rehab", Dickinson was a judge on Tyra Banks' show "America's Next Top Model". Her own reality series, "The Janice Dickinson Modeling Agency" ran from 2006 to 2008.
